Answer:
whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:
Step-by-step explanation:
I think the answer to your first question should be:
30a²b - 30ab²
Your second answer is good
whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:
for example, 6a²b³c x 2abc = 6(2)(a²)(a)(b³)(b)(c)(c)
= 12a³b⁴c²
First, we see how many photos can be printed in a minute. We do know that it can print 28 photos in 8 minutes.
To find how many photos it can print in 1 minute, we divide 28 by 8.
28÷8=3.5
The printer can print 3.5 photos per minute.
To see how many minutes it will take to print 35 photos, we divide 35 by 3.5.
35÷3.5=10.
It will take 10 minutes to print 35 photos.
Have a nice day! :)
